What I wrote yesterday was correct but incomplete.
In addition to the file descriptors, dossrv is holding
up a reference to the window's name space, in which
the window files are still accessible.  If you do

	slay dossrv |rc  # clean slate
	unmount /mnt/wsys /dev
	unmount /mnt/wsys
	9fat:
	exit

then the window does in fact disappear.
